$PECIPICATION forming part of Letters Patent No. 391,365, dated October 16, 1888.

Application filed April .2, 1888.

.To aZZ whom it may concern:

Be it known that 1, CHARLES M. GUMMER, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Gas-Burners for Stoves, Furnaces, Heaters, 850., of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to gas-burners for stoves and heaters of the character used in consuming natural or other gas.

The invention consists in the peculiar construction and combination of parts constituting the burner.

The object of the invention is to make a burner which can be cheaply and quickly replaced in whole or in part, which shall secure a complete intermingling of the gas and air, and shall cause aperfect and uniform combination.

Figure 1 is a top plan view of the burnercasing with coupling attached, but with cover and diaphragm removed. Fig. 2 is a crosssection of the mixing-chamber of the burner with cover and diaphragm in place. Fig. 3 is a top view, and Fig. 4 a bottom view, of the diaphragm.

The letter a indicates the supply-pipe. This is connected by a coupling, b, to a gas-supply pipe, and the mixed gas and air are fed to chamber 0, as usual. The chamber a is cupshaped, and is preferably of cast metal. The bottom of the cup is strengthened by ribs d d,

recess, f, externally of the bottom of the cup, to contain a nut, g, and prevent the turning of said nut.

The supply-pipe enters the cup or chamber a at one side. The cup has a number of ribs, i t, on the inner surface of the bottom extend ing up to a level above the opening made by pipe a. The ribsvlform supports for the edges of a disk or perforated diaphragm, K, which diaphragm has bosses Z, or equivalent stops, extending from its lower face between the ribs, to prevent the diaphragm from turning. The upper face of the diaphragm has a number of shallow cups, n, preferably three in number, to support the legs 0 of cover 0. The diaphragm on has a perforation, wt, preferably Serial No. 269,254. (No model.)

trefoil in shape, (as that form preserves the strength of the diaph ragm-plate, while extending with uniform width between the three legs of the cover.) The cover 0 is somewhat convex on its upper surface and concave below. The legs 0 rest in the shallow cups a when the parts are assembled, the flange p of the cover being supported by the legs just above the top of cup 0, thus leaving a narrow annular opening, q, quite around the top of the burner.

The cover 0 and the diaphragm m are held to the casing by a bolt or screw, 0", passing from the top of the cover through a hole in the bottom, where it enters the nutg in recess f, firmly securing the parts together. A boss, S, at one side of cup receives the end of inflow-pipe a.

The gas or mixed air and gas entering the cup or chamber 0 below the diaphragm is diffused. In rising through the passage m the 0 original currents are broken up. The mixed gas then rises against the cover and is deflected outwardly, so that it escapes at the annular opening g on all sides of the burner with a pretty uniform pressure. When ignited at this opening, the blaze will surround the entire circle.

The various parts are very cheaply made and quickly assembled, and the burner gives excellent economical results. The cup 0 is flared toward the top for convenience in construction and assembling.

I claim- 1. Thecombination,with agas-feeding pipe, of a cup-shaped mixing-chamber, a perforated diaphragm inclosed within said chamber, and a cover supported on said diaphragm and having its edges extending over the edge of the cup, substantially as described.

2. The combination, with the cup having 0 internal ribs and an entrance-opening near the bottom, of the perforated diaphragm m, supported on said ribs, and the cover 0, having its edge extending over the top of the cup, and having legs resting on the diaphragm.

3. The combination, in a gas-burner of the character described, of the cup 0, having supply-opening near the bottom, the perforated diaphragm m, supported therein, the cover 0, having legs resting on said diaphragm, and IQQ the binding-screw r, having nut 9 below the its nut in a recess in the bottom of the cup, 10 cup, all substantially as described. all substantially as described.
